Answer:
Step-by-step explanation:
The tangent segment is perpendicular to the diameter, so the triangle is a right triangle (not just based on its appearance). A property of circles is: a tangent is perpendicular to the radius drawn to the point of tangency.
In the right triangle, one leg has length 12.6, and the hypotenuse has length 21.
Apply the Pythagorean Theorem: (leg)^2 + (leg)^2 = (hypotenuse)^2
Oh, and the diameter has length 2x!

Step-by-step explanation:
Answer:
or
is a factor of the given polynomial.
Step-by-step explanation:
Let us learn the concept with an example first.
Let the polynomial be a quadratic function
.

The roots of
are 2 and 3.
Putting 
Putting 

Putting x = 2 or x = 3, g(x) = 0
The roots of equation g(x) are 2 and 3.
Now, let us try to factorize g(x):

so, the equation can be written as:
where 3 and 2 are the roots of equation.
The factors are (x-3) and (x-2).
for the polynomial f(x) which has roots
will have a factor:
or
